How do you remember the way to your house? Where do dreams come from? It is your brain(大腦) that does these things. A British scientist showed that “sleep can improve one’s memory.” It’s not a dream for students to study when they sleep. In fact, your brains is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(天才按鈕)” in the human brain. It might make a person more talented.
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠) keeps our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
Eat healthy food.
Get a lot of playtime or exercise.
Don’t drink or smoke.
Use your brain a lot.

The cost of medical care in the United States is very high. The time and money that doctors spend on their medical education is probably one reason for this problem.
A visit to a doctor’s office costs from 15 to 50 dollars. It’s so expensive. Many people in the United States think that doctors are overpaid. However, most doctors disagree. They say that they were asked to study medicine for a long time. Tuition for many years of medical education costs a lot of money. Doctors say that it is necessary for most medical students to borrow money from the bank to pay their tuition. Because their money must be repaid to the bank, young doctors need to receive a lot of money for their work. So they charge(收費(fèi))people high prices for medical care.
Therefore the cost of medical care in America is high. Because high tuition is one cause of high costs, one way to lower costs would be to have medical school that are free or have low tuition.
小題1:The underlined word "tuition" in the passage means “______”

A．eating at school	B．studying the courses
C．money used for education	D．living at school

小題2:The main idea of the passage is that______.

A．a(chǎn) visit to a doctor’s office may cost much in the USA

B．the cost of medical care is the only reason for the high costs in the USA

C．medical care in the USA costs a lot of money because doctors want to be rich

D．the high cost of tuition in medical schools is one reason for the high cost of medical care in the USA

小題3: The cost of medical care in the USA is very high. What does the writer think about it?

A．He agrees that doctors are overpaid.

B．He thinks it is a big problem and suggests (建議) solving (解決) it.

C．He doesn’t think the medical students should borrow money from banks.

D．He doesn’t think it necessary for the medical students to study for a long time.

What does it feel like to break a bone (骨頭)? It’s different for everyone, but the pain is often sharp (嚴(yán)重). If the break is small, however, the person may not feel much pain at all. If you think that you or someone else has broken a bone, the most important things to do are to stay calm, make the hurt person comfortable, and call the doctor. Do not move the injured body part since movement could make it worse.
To treat the break, the doctor will need to take an X-ray. This gives the doctor the information he or she needs to set (接上) the bone: to put it back to its normal place. If the bone is large or it is broken in more than one place, the doctor may need to use metal pins (鋼釘) to set it. After the bone has been set, the next step is usually putting on a cast, the special, hard thing that will keep the bone in place for a month or two.
Your bones are excellent at healing themselves. Broken bones will produce many new cells (細(xì)胞) and tiny blood vessels (血脈). These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.
小題1: Which of the following is the best title for the passage?

A．How to Know if a Bone is Broken

B．How Broken Bones Heal Themselves

C．Common Causes (原因) of Broken Bones

D．What You Should Know about Broken Bones

小題2: When someone breaks his bone, the following should be done except ______.

A．a(chǎn)sking the doctor for help	B．comforting the hurt person
C．moving the injured part	D．staying calm

小題3:Which is the correct order to treat the break?
a. take an x-ray b. use metal pins to set it c. put it back to its normal place d. put on cast

A．a(chǎn)→b→c→d

B．a(chǎn)→c→b→d

C．a(chǎn)→d→c→b

D．d→a→b→c

小題4:The underlined word “heal” in Paragraph 3 is closest in meaning to “______”.

A．break again

B．become worse

Everyone has got two personalities (性格) —the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control yourself, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you go to sleep.
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by new ideas. You don’t like to make people unhappy, so you never express your real feelings. You’re quite shy and you aren’t very confident.
If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you’re always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not for tomorrow.
If you sleep on curled up (蜷縮), you are probably a very nervous person. You have a low opinion of yourself and often protect yourself from being hurt, so you are very defensive. You’re shy and you don’t usually like meeting people. You like to be on your own.
If you sleep on your side, you have usually got a well-balanced (平衡的) personality. You know your strengths and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel worried, but you don’t often get unhappy. You always say what you think, even if it makes people angry.

We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you to live a green life.
Remember these three words: reduce, reuse and recycle.
Reduce means “use less”. Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think if it is really necessary or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should take care of them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup or a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
Recycle means “change things into something else”. Although it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
Title: 46 to Live a Green Life

We produce waste every day and it is 47 to us. We can do something to help.
